DISTILLIN'G OR RECTIFYING COLUMN.

Specification of Letters Patent.

Patented Nov. 10, 1908.

Application filed March 11, 1908. Serial No. 420,526.

and useful Improvements in Distilling or Rectifying Columns; and I do hereby declare the following totbe a full, clear, and

exact description of the inventlon, such as will enable others skilled in the art to which it appertains to make ai'iid use the same.

My invention relates to distilling or rectifying columns for alcohol, petroleum, etc., and more especially at the refrigerating means used in said coluni s, the object being to check the rise of the vgpor's and to force them totravel in a tortuo rl's course.

With this object in t 'w, {my invention consists in the constructio of parts as hereinafter (1e In the accompanying drj virigsFigure l isa perspective view, par in section, of the lower part of a distill rectifying column. Fig. 2 is a persp 1v view, on a larger scale, of part of i frigerating means,and Fig. 3 is a sinilaview of a modified refrigerating means} 1 represents the baseof the column into which the vapors to be distilled or rectified are delivered through the-[pipe 2. This column is crossed by platesf'3 :having upwardly extending tubes 4, of'the' usual construction.

Transversely through the column pass series of pipes 5, through which air or water is passed, by any suitable meansfnot shown,

for the purpose of refrigerating the vapors. Above-the lower row of the pipes 5 are arranged a series of curved battle plates 6, separated from each other by a space, such as 8, and above the series of baflie plates 6 is arranged another series of battle plates 7, leaving between them a space 9, but'this second series of battle plates is arranged so as to break joints with the lower series. Above each of the spaces 9 is arranged a cooling tube 5 and above these tubes are ,arranged roof-like structures consisting of a top 10 and sides 11 provided with perforations 12, the effect of this structure being to cause the vapors to travel in a tortuous .passage, as shown by the arrows in Fig. 2, thereby facilitating the condensation of matters carried along with the alcoholic or other vapor. The cooling tubes 5 under the rooflike structures may be omitted, as shown on the left of Fig. 2.

In Fig. 3 a modified form is shown. Between the spaces left between the pipes 5 are located baflie plates 13, leaving spaces 14 be: tween them. Resting on two of the adjacent baflle plates 13 and encircling the tubes 5, is a roof-like structure having a curved lllll'JOlfOl'tttG top 15 and curved sides 16 provided with slots 17. Joining each pair of these roof-like structures is a curved plate 18 provided with slots 19, the effect of this construction being to cause the vapors to travel in a tortuous course as-indicated by arrows in Fig. 3, thereby facilitating the purification of the vapors.

Having thus described my invention, I claim 1. In a distilling or rectifying column, the

tubes passing through said shell, and means for causing the vapors, as they rise in said shell, to travel in a tortuous course, consisting of baflle plates, slotted roof-like structures supported on said battle plates, and slotted plates supported on said roof-like structures, substantially as described.

In testimony whereof, I aflix my signature, in presence of two Witnesses.
